Analysis and preventive measures of excitation system failure leading to two downtime accidents

Abstract

For the fault of rectifier bridge filter of excitation system and fault of 24V power supply of excitation system, the unit was shut down twice, by analyzing the causes, the preventive measures for excitation system operation are formulated, meanwhile, it is found that the equipment management of excitation system is not deep enough and the training of excitation system is not in place. It is proposed to carry out in-depth equipment operation and maintenance control, strengthen the excitation system knowledge training, increaseing the excitation system inspection frequency and other improvement measures, such as deal with the similar problems to the scene and engineering technical personnel to provide useful experience and processing basis.
